摘要（英）：

The utility model discloses a novel drive circuit of an inverter welding power supply. The novel drive circuit can avoid an amplification area of an IGBT. The circuit comprises a transformer, an MOS tube and a capacitor. One end of a secondary coil of the transformer is connected with a grid electrode of the MOS tube through a first resistor. Wherein one end of the capacitor is connected with thesource electrode of the MOS tube, the other end of the capacitor is connected with the source electrode of the MOS tube, the drain electrode of the MOS tube is connected with one end of the capacitorthrough the second resistor, the other end of the capacitor is connected with the grid electrode of the IGBT tube, and one end of the capacitor is further connected with the emitting electrode of theIGBT tube.
